This just cannot be good for Microsoft. I don't see how this turns around. Windows 8 and the Surface are just not getting the traction expected to maintain their monopoly. For entrepreneurs, though, this creates a lot of opportunity. It also does for Apple, Amazon, and Google, of course.

One of my favorite books is The Innovator's Dilemma and here it is in action again. I consider this a must read for entrepreneurs. It will give you the confidence to go from a perspective of "that's already been done before" to "that's already been done before and can be disrupted because of the dependency on the old order" (Who Moved My Cheese?).
